This is a Common Lisp library providing logging faciltiy similar to CL-LOG and LOG4CL.

This Common Lisp package offers functions for parsing and formatting decimal numbers. The package's main interface are the functions parse-decimal-number and format-decimal-number. The former is for parsing strings for decimal numbers and the latter for pretty-printing them as strings.

Wayflan is a from-scratch Wayland communication library for Common Lisp. It makes a good-faith effort to mimic libwayland behavior not defined in the Wayland spec, to keep compatibility between the two libraries.

Wayflan is not a compositor nor a GUI toolkit. Its purpose is to parse Wayland protocol XML documents and exchange Wayland messages between other processes.

Features:

• Client support

• All implementation done in Common Lisp from the socket up

• Enum values are translated into keywords

• Wayland protocol introspection

• ASDF component :wayflan-client-impl generates code from XML. ASDF's extensible components make it possible to teach your program new protocols for Wayland without the need of a special build system.

MT19937 is a portable Mersenne Twister pseudo-random number generator for Common Lisp.

Screamer is an extension of Common Lisp that adds support for nondeterministic programming. Screamer consists of two levels. The basic nondeterministic level adds support for backtracking and undoable side effects. On top of this nondeterministic substrate, Screamer provides a comprehensive constraint programming language in which one can formulate and solve mixed systems of numeric and symbolic constraints. Together, these two levels augment Common Lisp with practically all of the functionality of both Prolog and constraint logic programming languages such as CHiP and CLP(R). Furthermore, Screamer is fully integrated with Common Lisp. Screamer programs can coexist and interoperate with other extensions to as CLIM and Iterate.

This library is an SDL wrapper as part of an umbrella project that provides cross-platform packages for building large, interactive applications in Common Lisp.

Simple and fast marshalling of Lisp datastructures. Convert any object into a string representation, put it on a stream an revive it from there. Only minimal changes required to make your CLOS objects serializable.

The purpose of this library is to provide a collection of implementations of trees.

In contrast to existing libraries such as cl-containers, it does not impose a particular use for the trees. Instead, it aims for a stratified design, allowing client code to choose between different levels of abstraction.

As a consequence of this policy, low-level interfaces are provided where the concrete representation is exposed, but also high level interfaces where the trees can be used as search trees or as trees that represent sequences of objects.

PAX provides an extremely poor man's Explorable Programming environment. Narrative primarily lives in so called sections that mix markdown docstrings with references to functions, variables, etc, all of which should probably have their own docstrings.

The primary focus is on making code easily explorable by using SLIME's M-. (slime-edit-definition). See how to enable some fanciness in Emacs Integration. Generating documentation from sections and all the referenced items in Markdown or HTML format is also implemented.

With the simplistic tools provided, one may accomplish similar effects as with Literate Programming, but documentation is generated from code, not vice versa and there is no support for chunking yet. Code is first, code must look pretty, documentation is code.

lparallel is a library for parallel programming in Common Lisp, featuring:

• a simple model of task submission with receiving queue,

• constructs for expressing fine-grained parallelism,

• asynchronous condition handling across thread boundaries,

• parallel versions of map, reduce, sort, remove, and many others,

• promises, futures, and delayed evaluation constructs,

• computation trees for parallelizing interconnected tasks,

• bounded and unbounded FIFO queues,

• high and low priority tasks,

• task killing by category,

• integrated timeouts.

This package provides a collection of types, functions and macros. Some of the functionality is implemented from Graham's On Lisp and Seibel's Practical Common Lisp.

The py-configparser package implements the ConfigParser Python module functionality in Common Lisp. In short, it implements reading and writing of .INI-file style configuration files with sections containing key/value pairs of configuration options. In line with the functionalities in the python module, does this package implement basic interpolation of option values in other options.

This package provides an extensible implementation of defclass that can accurately control the expansion according to the metaclass and automatically detect the suitable metaclass by analyzing the defclass form.

TRIVIAL-TYPES provides missing but important type definitions such as PROPER-LIST, ASSOCIATION-LIST, PROPERTY-LIST and TUPLE.

fast-websocket is an optimized low-level WebSocket protocol parser/composer.

This package provides a grab bag of miscellaneous Common Lisp utilities.

SEEDABLE-RNG provides a convenient means of generating random numbers that are seedable with deterministic results across hardware and Common Lisp implementations.

This package provides the Common Lisp part of the emacs-slite test runner.

This library provides an OS and implementation independent access to timeouts.

Scrape on-line documentation out of a running Lisp image.

This package provides Common Lisp system collecting tools written to wrangle OpenGL Shader Language (GLSL) source files.

This library provides an OS and implementation independent access to timeouts.

jsown is a high performance Common Lisp JSON parser. Its aim is to allow for the fast parsing of JSON objects in Common Lisp. Recently, functions and macros have been added to ease the burden of writing and editing jsown objects.

jsown allows you to parse JSON objects quickly to a modifiable Lisp list and write them back. If you only need partial retrieval of objects, jsown allows you to select the keys which you would like to see parsed. jsown also has a JSON writer and some helper methods to alter the JSON objects themselves.

Trivia is a pattern matching compiler that is compatible with Optima, another pattern matching library for Common Lisp. It is meant to be faster and more extensible than Optima.
